Abstract
The invention relates to a battery lead of a portable phone. The lead is made from metal, the surface of the lead or at least the surface of the lead connected with other parts is subjected to copper doping treatment, a copper doped layer is 5-200 nanometers in thickness, and the amount of doped copper is 25-80 milligrams per square centimeter. With adoption of the copper doping treatment, the electric conductivity of the lead is improved, in addition, due to improvement of the electric conductivity and improvement of strength of the lead due to application of iron or stainless steel, the thickness and width of the lead can be reduced, and the weight of the lead is reduced effectively.
Description
Technical field
The invention belongs to field of batteries, refer to especially a kind of battery lead of portable phone.
Background technology
In recent years, along with the extensive use of portable type electronic product, supporting battery also comes into one's own with it.And, along with the miniaturization of electronic product, the trend of lightness, occupying critical positions for it provides capacitance and the weight of the secondary cell of electric energy aspect miniaturization of electronic products and the lightweight, particularly lithium ion battery is extensively more important to the requirement of battery as the power supply of small portable electronic product.The battery of portable phone includes battery main body, protective circuit, the metal lead wire between battery main body and protective circuit, input and output terminal and shell.Wherein, for metal lead wire, its connection with other parts is realized by spot welding usually, because spot welding does not almost have thermal impact and welding efficiency height to battery or other parts.
The battery lead of existing portable type electronic product is nickel down-lead basically, and the conductance of nickel is not high in fact, but the reason that can generally use is that its weld strength and stability can reach requirement, and conductance surpasses iron or stainless steel etc. after all.And the words of considering from conductance, copper or silver are optimal selections, but the weld strength of copper or silver and stability are low, cause battery because the failure rate of weld strength and stable aspect is too high and can't satisfy instructions for use, and the ratio of copper or silver is great, is unfavorable for the lightweight of battery.
Prior art proposes with the next lead-in wire as this class battery of aluminum or aluminum alloy, although the light specific gravity of aluminum or aluminum alloy can adapt to light-weighted requirement, and the conductance of aluminium is also high than nickel, should be good selection, still, aluminum or aluminum alloy also exists weld strength and the low problem of stability.Prior art proposes using the aluminum or aluminum alloy lead-in wire to improve, its main technical schemes is to come as connector at the metal that the one or both ends of aluminum or aluminum alloy lead-in wire arrange except aluminum or aluminum alloy, come to connect and accept soldering with other parts by connector, can improve pad intensity and welding stability like this, the metal or alloy except aluminum or aluminum alloy of its selection mainly is nickel, iron and stainless steel.This improvement technology can realize reducing the weight of battery lead, but there is serious defective in this technology, this defective is exactly because the metallic conductivity of connector is lower than aluminum or aluminum alloy, therefore can affect the discharge of battery and under the long electric power thus supplied of battery, have a large amount of heat generations, can affect the life-span of battery or even electronic product.
Summary of the invention
The purpose of this invention is to provide a kind of technical scheme, this technical scheme can solve the light-weighted a large amount of generations that reduce simultaneously the battery heat of battery, and has realized substituting existing nickel down-lead or aluminum or aluminum alloy lead-in wire by iron or the ferroalloy lead wire of cheaper.
The present invention is achieved by the following technical solutions:
The battery lead of portable phone, described lead-in wire is made of metal, and on the surface of lead-in wire or be that the face that is connected with other parts adopts and mixes copper and process at least, the described thickness of mixing the copper layer is the 5-200 nanometer, and mixing the copper amount is every square centimeter of 25-80 milligram.
Described lead-in wire metal is iron, ferroalloy or stainless steel.
More preferably, the described thickness of mixing the copper layer is the 15-40 nanometer, and mixing the copper amount is every square centimeter of 40-75 milligram.
Described phone lead-in wire is banded structure.
The beneficial effect that the present invention compares with prior art is:
Result after employing is mixed copper and processed is the conductance that has increased lead-in wire, and because the raising of conductance and uses iron or stainless steel has improved intensity as lead-in wire can reduce thickness and the width of lead-in wire, has effectively reduced the weight that goes between.
Embodiment
The below describes embodiments of the invention in detail, and the embodiment that the following describes is exemplary, only is used for explaining the present invention, and can not be interpreted as limitation of the present invention.
The iron, ferroalloy or the stainless steel base that use in the present invention are identical with prior art, therefore just are not described in detail.
The existing technology lead-in wire of mentioning in this application all refers to make lead-in wire and the general name of the connector that made by iron, nickel or stainless steel with aluminum or aluminum alloy, and the weight of described existing lead-in wire also refers to above-mentionedly make the total weight that lead-in wire adds the connector that is made by iron, nickel or stainless steel with aluminum or aluminum alloy.
Embodiment 1
Battery lead at portable phone of the present invention, described lead-in wire is made of metal, wherein the shape of lead-in wire is decided by actual needs, in the present embodiment, lead-in wire be shaped as band shape, described lead-in wire is that iron, ferroalloy or stainless steel are made in the present embodiment, specifically adopts which kind of material can disregard final impact effect present stage of present techniques scheme, therefore just to adopting iron, ferroalloy or stainless concrete difference not to be elaborated.
What adopt is to mix copper technology in one side.What adopt in this application is the copper-iron alloy of mixing copper technology rather than use, its reason is, some copper-iron alloy improves a lot than iron or stainless steel aspect conductance really, but be implemented in and improve conductance in the limited area, the essential ratio that increases copper in the copper-iron alloy, generally need to contain the copper that is not less than 20% mass percent, and be that whole connector all needs such alloy, last result is that the conductance and the weight reduction that improve are limited.Certainly, also can realize the purpose of inventing if make connector with copper-iron alloy, but not be optimal selection.
On the surface of cable or be that the face that is connected with other parts adopts and mixes copper and process at least, the described thickness of mixing the copper layer is 15 nanometers, and mixing the copper amount is 40 milligrams every square centimeter.Prepared wire widths is 0.6 times of wire widths of prior art, and through measuring, three average weights of this lead-in wire are 0.85 times of existing width lead-in wire weight; Through detecting, its conductance is 58.3, far above the conductance of aluminum or aluminum alloy.
The copper of mixing described in the application is processed take the electronics sputtering method as the best approach, can certainly adopt and when making iron or stainless steel substrate, carry out heat and mix copper method, but the skewness of mixing copper layer and copper that the method obtains, conductance is also inhomogeneous, is not optimal selection.
